Surface Mount - Reflow solderable

World's smallest and thinnest size (4.7 x 4.7 x 2.4mm)
Only lead-free soldering reflow surface mounting model in the industry
High sensitivity
Achieves excellent electromagnetic noise suppression performance
Contributes to flatter equipment design with simultaneously developed flat lens

Requirements for human presence sensing are increasing in various applications such as energy conservation, theft prevention, appliances and care-giving. Previously, pyroelectric infrared sensors used in human presence sensors tended to be large, and unsuitable for automatic surface mounting due to lead mount construction, making them less cost effective and difficult to mass-produce. To this end, Murata previously offered the only lineup of reflow surface mount pyroelectric infrared sensors in the industry. Murata were able to further reduce the size of this newly developed "IRS-B series" model, creating a smaller and thinner version, by improving package technology and pyroelectric ceramic materials. This model makes it possible to mount the human presence sensor on

equipment allowing the equipment to be smaller, thinner and lighter, such as appliances, low profile digital equipment, PCs and video game consoles.

IRS-B series is approximately 50% smaller in volume and 10% thinner than the previous surface mount model. Compared with common lead-type models, it is significantly smaller with a lower profile approximately 20% less in volume and 50% less in thickness than the former.

Curvature of the "flat lens," developed together with "IRS-B series," was made extremely flat making it possible to streamline the equipment design.
